Mix the egg yolks with sugar, add flour, sugar and cold butter (in small pieces) and knead until obtaining a smooth and compact dough (if you don't like wholewheat flour you can replace it with the spelt or 00 one). Wrap the dough in the film and let stand in refrigerator at least 30 minutes. Roll out the pastry with a rolling pin and place it in the tarts pan (we bath the ovenpaper, sqeeze it well and settle in the pans so that it will be easier to remove the tarts once cooked). Put something on the dough (while cooking) as a weight just to keep the shape of the pastry (we place ovenpaper to protect the dough and some pasta as weight)and bake at 180°C in preheated oven (static top and bottom) for 20/25 minutes or until Golden Brown. Remove from oven and let cool. This dough is perfect to make cookies too.

Wash the strawberries, season with lemon and sugar and let stand for few minutes...you can leave them Whole or cut into slices and decorate as you wish.You can replace strawberries with thin slices of mango or ananas and a splash of lemon for a tropical taste(in this case we suggest you few drops of rum in the mascarpone cream)!

Preparare le crostatine riempiendole di crema mascarpone e decorandole con la frutta e qualche goccia del loro succo. Servitele subito per mantenere tutta la croccantezza della frolla o preparatele in anticipo e conservatele in frigorifero (tirandole fuori qualche minuto prima di servire) lasciando che la pasta assorba il succo e il profumo delle fragole o della frutta che avete scelto. Sono perfette come dessert e davvero carine per un party con buffet!Prepare the tarts filling with the mascarpone cream and decorating with fruit and few drops of their juice. Serve at the time retaining all the crispness of the pastry or prepare them in advance and store in the refrigerator (pull them out few minutes before serving) allowing the pastry to absorb the juice and the smell of the strawberries or the fruit you have chosen. They are perfect as dessert and really pretty for a party buffet! Enjoy!
